Polypropylene (PP) has had a remarkable growth rate during the last 30 years, and today it continues to be the fastest growing of the thermoplastic polyolefins. This has resulted from both progress in Ziegler-Natta catalytic systems and production technologies, together with an ease of post-treatments that can modify its structure and broaden its field of application. Today, we are presenting some recent innovations that are based on a methodology of advanced, 4th generation catalysts (Reactor Granule Technology), on retailoring post-treatments (Hivalloy, foamable PP), and on polymer/processing machinery developments (PP stretch-blow molding).
